Your Perineum: Understanding This Vital Area

It’s one of those body parts we don’t often talk about, is it? But when something feels off “down there,” it suddenly becomes very important. I’ve had patients, especially new moms or those experiencing discomfort, come in feeling a bit shy but also really needing answers about this small, yet significant, patch of their body. We’re talking about the perineum. It’s that little area of skin and underlying tissue nestled between your genitals (that’s the vaginal opening for women or the scrotum for men) and your anus. But it’s more than just skin; it’s also the base of your pelvic cavity.

What Exactly is My Perineum?

So, let’s get a clearer picture. When we say perineum, we might mean the visible, sensitive skin you can feel. Or, we could be talking about the deeper structures that sit right under your pelvic floor muscles. Think of it as a bit of a foundation.

It’s a small area, for sure. For women, it’s usually around 1.5 inches long. For men, a bit longer, maybe 2 inches or so. Underneath that skin, there’s a lot going on – layers of connective tissue, some fatty tissue, muscles, and membranes. A really important nerve, the pudendal nerve, runs through this area, branching out to your genitals, pelvic floor, and anus. This nerve network is why the perineum is sensitive and plays a role in sexual sensation, as well as helping you control when you pee and poop.

Where is it and What’s its Structure?

Okay, anatomy time, but let’s keep it simple.

Imagine your pelvis. The perineum starts at the front, at a joint called the pubic symphysis (where your left and right pelvic bones meet), and it stretches all the way back to your tailbone, or coccyx. Sideways, it reaches out to those bones you feel when you sit – your “sitz bones” (or ischial tuberosities, if you want the fancy term).

If you were to draw its boundaries, it would look a bit like a diamond. We often divide this diamond with an imaginary line into two triangles:

The urogenital triangle at the front: This holds your genitals and your urethra (the tube that carries urine out) and the muscles around them.
The anal triangle at the back: This contains the opening of your anus and the anal sphincter (the muscle that helps you control bowel movements).

Right where these two triangles meet, there’s a tough bit of tissue called the perineal body. It’s a key player in supporting your pelvic floor, and it’s an area that can sometimes be injured, especially during childbirth.

What Does the Perineum Do?

Your perineum isn’t just there; it has some important jobs:

Sensation: As I mentioned, it’s an erogenous zone thanks to all those nerve endings. It contributes to sexual arousal and response.
Support: It forms a base that helps support your pelvic floor muscles. These muscles are crucial because they hold your bladder, colon, and reproductive organs in place.
Function: The internal structures of the perineum are involved in urination, bowel movements, and sexual intercourse.
Childbirth (for women): The perineum stretches significantly during vaginal birth.

When Things Go Wrong: Perineum Conditions

Because it’s such a busy and sometimes vulnerable area, the perineum can experience a few issues. Childbirth is probably the most common reason for perineal injury, with many women experiencing some degree of tearing. But problems can affect anyone.

For Women:

Vaginal Delivery Tears: As a baby passes through the birth canal, the vagina and perineum stretch. Sometimes, they tear. Most tears are minor and heal well, sometimes needing stitches. More significant tears can affect nearby pelvic floor muscles or the anal sphincter, which can make it tough to pee, poop, or have comfortable intercourse for a while.
Episiotomy: This is a cut made by a doctor or midwife in the perineum during childbirth, intended to widen the vaginal opening. It used to be pretty routine, but we do them much less often now. We’ve learned that for some, an episiotomy might actually increase the risk of pelvic pain and incontinence later on.

For Men:

Prostatitis: If the prostate gland becomes inflamed (often due to infection or injury), you might feel pain in your genitals and your perineum.
Surgery: Sometimes, a surgeon might need to make a cut in the perineum to operate on the prostate, remove a tumor, or repair a urethral stricture (a narrowing of the urine tube).

For Everyone:

Pelvic Floor Dysfunction: Injury to the perineum can sometimes lead to trouble controlling your pee or poop.
Perineal Cysts or Abscesses: You can get these infected lumps on the perineum or inside the anus. They’re usually red, swollen, and pretty painful.
Hemorrhoids: These are swollen veins in your rectum or anus. They can be internal or poke out, causing bleeding, itching, or pain in the perineum, especially around bowel movements.
Pudendal Nerve Entrapment: If that pudendal nerve gets pinched or inflamed, it can cause perineal pain that might come on suddenly or build up over time.
Referred Pain: Sometimes, pain you feel in your perineum is actually coming from somewhere else. Things like appendicitis, colitis, or other gut issues can sometimes cause pain that radiates to this area.
Fournier’s Gangrene: This is a rare but serious bacterial infection where the skin of the genitals and perineum starts to die. It’s more common in men, particularly those in their 50s and 60s who have diabetes. It needs urgent medical attention.
Injury or Trauma: Activities like motorcycling, cycling (especially with certain seats), or horseback riding can sometimes injure the perineum.
Sexual Abuse: Sadly, a torn perineum can sometimes be a sign of sexual violence.

What Should I Look Out For?

Pain is the most common red flag. If you’ve just had a baby, pain from a tear can make walking or sitting uncomfortable. Other signs that something might be up with your perineum, or the bits around it, include:

Trouble peeing or pooping.
A sore or itchy perineum.
Difficulty getting an erection (for men).
Pain when you pee or during intercourse.
A lump, redness, or swelling on your perineum.

How Do We Check Your Perineum?

If you come to see me with concerns, I’ll usually start with a gentle physical exam. This might include a digital rectal exam (where I carefully insert a gloved finger into your rectum) to feel for anything unusual.

Sometimes, we need a closer look inside. Imaging tests can help us diagnose what’s going on:

CT Scan: Can show internal injuries.
MRI: Good for looking at blood vessels or muscles.
Ultrasound: Can also show damaged blood vessels.
X-Ray with dye: Can help us see if there’s any damage to your urethra.

Caring for Your Perineum: Treatments and Tips

If you have a cut or tear, we’ll assess if you need stitches. But while you’re healing, or if you just have general discomfort, there are things that can help:

Sitz Bath and Warm Compresses: A sitz bath is just a shallow, warm-water bath. It’s great for cleaning the perineum and helping it heal. Try it twice a day for 5-10 minutes. Gently pat the area dry afterward – no scrubbing!
Pain Medications and Numbing Sprays: Simple painkillers like acetaminophen or ibuprofen can help. Numbing sprays or creams can also provide relief. If hemorrhoids are the issue, specific wipes and creams can soothe pain and itching.
Peri-bottle: This is a little squirty bottle you can fill with warm water. After using the toilet, you can gently spray your perineum to clean it instead of wiping, which can be gentler.
Constipation Prevention: Straining during bowel movements will make perineum pain worse. A high-fiber diet and drinking plenty of water (aim for at least 8 cups a day) are your best friends here.
Pelvic Floor Exercises (Kegel exercises): Especially after childbirth, strengthening your pelvic floor muscles can really help with healing. I might refer you to a physical therapist who specializes in this. But, and this is important, only start Kegels after an injury with your doctor’s okay.

For infections, we might prescribe antibiotics. If there’s an abscess, it might need to be incised (cut) and drained. Severe hemorrhoids or nerve damage might occasionally need surgery.

Can Massaging My Perineum Prevent Tears During Childbirth?

This is a question I get a lot from expectant moms! While you can’t completely prevent tearing, perineal massage before and during labor can reduce the chances of a tear, or make a tear less severe.

When to start? Around week 34 of your pregnancy is a good time.

How often? Aim for about three to four times a week, for about five minutes each time.

How to do it?

It’s all about finding a comfortable, relaxed position. Make sure your hands are clean.

Lie on your back, well-supported, with your legs wide and knees bent.
Use a natural oil (like coconut or olive oil) or a water-soluble lubricant (like K-Y Jelly® or Astroglide®) on your fingers, thumbs, and your perineum.
Gently insert one lubricated thumb about 1 to 1.5 inches into your vagina. Then, gently insert your other thumb.
Press both thumbs down towards your anus, on the back wall of your vagina. You should feel a gentle stretch inside. Hold this for a minute or two.
Slowly move your thumbs in a U-shape, maintaining that gentle stretch.

It might feel a little strange at first, but many women find it helpful.
